近年来,鉴于有关超基性岩和基性岩的矿物成分的大量实际资料以及有关金刚石包体矿物学研究和金伯利岩形成过程模拟实验研究的新情报的积累,人们对金伯利岩的研究兴趣日益增加。这一切使得有必要对现有资料进行重新研究。现今对于金伯利岩岩筒中超基性岩和榴辉岩的成因,存在两种基本观点。一些研究者把金伯利岩岩筒看作是穿到地幔深处的、把呈 In recent years, there has been an increasing interest in the research of kimberlites in view of the large amount of actual data on the mineral composition of ultrabasic rocks and basic rocks, as well as the accumulation of new intelligence on the study of diamond inclusions and kimberlite formation processes increase. All this makes it necessary to re-examine existing information. There are two basic ideas for the genesis of ultramafic rocks and eclogites in the kimberlite barrels. Some researchers see the kimberlite rock as being worn to the depths of the mantle
